constructor

    1. In object-oriented languages, a function
   provided by a class to initialise a newly created object.  The
   constructor function typically has the same name as the class.  It
   may take arguments, e.g. to set various attributes of the object
   or it may just leave everything undefined to be set elsewhere.

   A class may also have a destructor function that is called when
   objects of the class are destroyed.

   2. In functional programming and type theory, one of the
   symbols used to create an object with an algebraic data type.
